I wanted to test an old Minolta MD mount macro lens out on my Sony SLT. I bought an adapter on ebay and it just arrived. Adapting an MD mount to an Alpha mount lens is akin to adapting FD to EF in the Canon line. Unless you buy an expensive adapter with glass, it is a no go. I found a $29 adapter that will allow this lens to work at close distances, which is all that is needed for macro work (it won't reach infinity). I tested it on a paper mache figure that I bought this winter at the Mexican Import market. No sharpening was applied. So now I have a 100mm f/3.5 macro. I already had the lens, but the total investment buying it used would only be about $200.
